True enough, although I don't think we'll adjusted is the right term. She did try to freeze all the time of gravity falls (which actually wouldn't have solved her problem) afterall.

But what Mabel wants most is to be around dipper and she'll have her friends there so shed probably manage. It at least sounds better than going home where it sounds like she has no friends. Also these kids don't seem to care about there parents at all but that's another matter entirely lol

It makes sense for dipper to stay though sense the fate of the world would most likely depend on him at least a little bit. Although if he was being less selfish Ford could have also offered to keep mable as well, I think Dipper should have suggested this then we could have seen Ford have a big negative reaction…
